258 Compression Test

[Kman]

I went to test the compression on the 258 and found that my Sears Compression Tester won't screw into the deeply recessed plug holes in a 258 head.Anybody know of a brand of tester that will work on a 258?

I went to Sears and they had a compression tester by Actron that had the deep recess adapter.It was $24.95.Afterwards I went to Advance Auto(NAPA was closed) and they had it for the same price.
